SAW-HANDLE.

SPECIFICATION forming part of Letters Patent No. 712,452, dated ctober 28, 1902.

Application filed May'26, 1902. Serial 110.108,91?. (No model.)

To a/ZZ whom t may concern: l

Beit known that I, JAMES CHAMBERs,a cilizen of the United States, residing at Everett, in the county of Snohomish and State of; Washington, have invented certain new and useful Improvements in Saw-Handles, 4of which the following is a s'pecilication, reference being had therein to the accompanying drawings.

This invention relates to saw-handles; and its object is to provide a simple, strong, and convenient device of this class efficient in its operation and `which can be 'applied or removed from a saw quickly. These and other objects are attained in the construction and combination of parts hereinafter fully described,illustrated in the accom panyin g d rawings, and nally pointed outin the claims.

In the said draWings,Figure 1 is a side elevation of the device applied t0 a saw. Fig. 2 is any end elevation thereof. Figs. 3 and 4 are perspective views of the stock S and guard G shown in the other views.

The stock S consists of a vertical plateweb 2, which at its top edge is turned over to form a hook 3 for embracing the back edge of a saw 4 when the blade thereof rests against the said web. Integral with the stock are lugs 5 and 6, which extend latterally from one side of its bottom edge to respectively receive a clamping-screw 7 and a guide-tongue 8, hereinafter referred to. Connected in a longi tudinal direction from the said `Web by a shank 9 is a vertically-arranged socket 10 for the reception of a wooden handle-stick 11.` A guard G, preferably of the same length as the stock-web 2, is formedwitha U-shaped' cross section and has intermediate ofA its length an upright post `12V for inserting into a gullet 13 between two saw-teeth, and to prevent any side displacement thereat when the parts are clamped together I notch the post end to form a seat or saddle 14E therein and preferably make the projecting ends 15 15 of unequal length. Extending transversely from the top edge'l of the guard is a lug 1'7, having an eye or aperture 18, through which is passed a clam ping-screw 7 to engage with a screw-threaded hole 2O of stock-lug 5.

`Positioned upon and firmly secured to the guard, so as lo be in line with an aperture 2l in lug G, is the guide-tongue 8, making a slidable iit'in the lastmamed aperture.

To assemble the parts, the guard G is Iirst placed upon the saw-blade, so that the said post will be seated in agullet, as before mentioned, and the guard-channel straddle the teeth. The stock is then placed in position over the back edge of the blade, so that the socket 2l thereof willengage with the said guide-tongue of the guard, when by inserting the clamping-screw through lug 17 and screwing into the threaded hole 2O the handle is firmly secured together and to the sawblade. To remove the handle, make a couple of reverse turns of the clamping-screw and the parts will spread sufficiently to permit the hook 3 of the stock being lifted over the back -edge of the saw-blade and the guard-post 12 mentum propels the operators `lower hand against the teeth, to be badlylacerated thereby; but by covering up' the end teeth by a suitable guard all danger of being cut is obviated.

A further advantage gained by this invention is in the provision of a rib upon both the `tooth and back edges of the saw, whereby the same may be firmly grasped when beginning Qa horizontal cnt, for it is a Well-known fact jthatsuch cuts cannot be started true and straight in felling large trees without thus grasping a saw, and consequently the supple- .mental rib-handles is a decided advance in the art. t-

A still further advantage gained by the invention, and one that will be appreciated by men engaged in felling big timberf7 'oftentimes from an elevated position on choppingboards, is the fact of the facility with which the handle can be disconnected from a saw,

whereby the blade may be removed lengthwise from the kerf without disturbing the Wedges used for throwing the tree and permitting the sawyers to get to a safe distance before the tree falls.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A saw-handle, comprising a stock connected integrally by a shank with a sticksocket and formed with a web having its upper edge turned over to make a hook for engaging the back edge of a saw, a saw-teeth guard of U-shaped cross-section, an upright post positioned intermediate the length `of said guard and provided 4with a notch at its upper extremity, a guide-tongue projecting vertically from a side of the guard and adapted to engage in a corresponding socket of the stock, and means to secure the said stock to the said guard, such means comprising a screw passing through a lug of the guard and engaging with a threaded lug of the stock, substantially as described.

2. In a saw-handle, the combination with a stock S comprising a stick-socket 10, a vertical web 2 provided at its Jtop edge with a hook 3, and lugs 5 and 6 projecting laterally from the lower edge of said web; of a sawteeth guard G of U-shaped cross-section provided with an upright post l2, a guide-tongue 8 adapted to engage with aperture in said stock-lug 6, a lug 17 projecting transversely from said guard, and a clamping screw 7 passed through an eye of last-named lug and engaging with a screw-thread in eye of said lug 5, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

JAMES CHAMBERS.
